I would like to test the BGS library for post-processing some short very static sequences. When I do that with OpenCV, I usually : -make a first pass with an...

Suboptimal cache flush policy when processing datasets

I do not understand some of the design choices of GDALRasterBlock::Internalize() Consider the following scenario : I create dataset1 and dataset2 I fill dataset1 I read dataset1 and write it...

Better doc for copy operations and performance implications

- a fused hal::cartToPolar[32|64]f() is used instead of sequential hal::magnitude[32|64]f/hal::fastAtan[32|64]f - ipp_polarToCart is skipped for in-place processing (it seems not to support it correctly) relates to #24891 ### Pull Request...
